To (all whom it may concern.-

Be it known that I, JOHN J. BUHOUP, of Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. My invention relates to improvements in oll-burners; and it consists more especially in the peculiarconstruction of oil-valve for regulating and equalizing the distribution of oil to the burner, so as to produce a uniform I5 sheet of flame at the mouth of the burner.

It also consists in suitable means for preventing the dripping of oil from the mouth of the burner.

It consists, also, in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of the burner. Fig. 2 is a vertical section on line m 00, Fig. 1. Fig. 3 is a horizontal section on line y y, Fig. 1. Figs.

4 and 5 are elevations of the oil-valve hereinafter more fully described.

The body of the burner A may be made in sections bolted together or, as shown in the 0 drawings, of a single casting.

B represents the mixing or eonnningling chamber, the side walls of which diverge toward the mouth or outlet of the burner, thus spreading the fuel and flame into a fan-shaped form.

C and D represent, respectively, air and oil supply pipes, that communicate wit-h the mixing or eommingling chamber 13 by means of passage ways or inlets c and (1, respectively.

10 These passage ways or inlets extend, preferably, the entire width of the rear end of the commingling or mixing chamber B, the oilinlet discharging somewhat forward of the air-inlet to prevent the possibility of oil entering the latter.

The air-supply is controlled by a valve. (Not shown.)

For regulating the supplyof oil to the mixin g-chamber and insuring an equal distribu tion of the same the entire widthof said cham- 5o ber a cylindrical or tubular valve E is provided. The construction of casting Aissuoh as to form a suitable seat for this valve, the casting or body of the device having a lateral opening at one or either side for the entrance and removal of the valve for cleaning and other purposes, such lateral opening or openings being screw-threaded internally for receiving a correspondiugly-threaded plug F. Plug E (or one of such plugs in case there are two) is pierced for the passage of the valvestem E to the outside of the body of the device, where it can be manipulated. Oil-valve E has a longitudinal peripheral groove, as at e, communicating with and distributing the ()5 oil to the interior of the valve by means of holes 6 e at opposite ends of the groove. Valve E also has a series of oritices 6 that are adapted to discharge into the oil inlet or passageway D, leading to the mixing-chamber. 7c The oil-valve shown in the drawings has a series of four outlet orifices at approximately equal intervals, and the relative arrangement of inlet and outlet orifices e e is preferably such that an orifice c discharges approximately midway between two orifices c \Vith such arrangement the equal distribution of oil to the mixing or commingling chamber is regulated to a nicety.

To prevent the dripping of oil, at the mouth of the burner is provided a series of holes or channels 0, extending from the air supply pipe or reservoir to a horizontal slit c in the front end of the burner, slit 0' extending the entire width of the mouth of the burner and being preferably enlarged next to the discharging ends of holes 0, as at 0 Slit c is plugged opposite the discharging ends of holes or channels o, as at 0 and preferably, also, at the sides, as at 0;, whereby the air discharged from holes or channels 0 is spread and distributed to all points widthwise the front of the burner and directs into the flame anyoil that would otherwise have dripped.

\Vhat I claim is- 1. In an oil-burner, the combination, with the mixing or commingling chamber having inlets for air and oil, respectively, of a tubular valve having a series of outlet-orifices adapted to register with the oil-inlet of the mixing or commingling chamber and having a longitudinal peripheral groove and an orifi'ce at either end of said groove for receiving and distributing the oil to the series of outletorifiees, substantially as set forth.

2. In an oil-burner, the combination, with the mixing or com mingling chamber having lnlets for oil and air, respectively, and an air supply pipe or reservoir, of a slit in'the front end of the burner below and extending ap-i proximately the entire Width of the mouth of the burner, substantially as indicated, one or more openings or channels leading direetly from the air supply pipe or reservoir to and discharging into said slit, and a plug or spreader located opposite the discharging end of said air channel or channels, substantially as set forth.

3. In an oil-burner, the combination, with a mixing or eommingling chamber having inlets for oil and air, respectively, and an air supply pipe or reservoir, of a slit in the front end of the burner below and extending approximately the entire Width of the mouth of l the burner, a series of openings or channels U.
